FIREPROOF CONSTRUCTION AND METHOD OF MAKING SAME.

SPECIFICATION forming part of Letters Patent No. 681,700, datedSeptember 3, 1901.

Application filed August 23, 1900. Serial Il'o` 27,751. (No model.)

T all whom, it may concern:

Be it known that LABRAHAM L. A. HIMMEL- WRIGHT, a citizen of the UnitedStates, residing at New York city, county of New York,

and State of New York, have invented certain new and useful Improvementsin Methods of Making Fireproof Constructions, fully described andrepresented in the following specification and the accompanyingdrawings,

lo forming a part of the same.

The object of the present invention is to provide an improved fireproofpartition and method of making the same; but the invention is applicablealso wherever it is desired x5 to use a similar vertical fireproofconstruction, the especial object of the invention being to provide astrong and durable construction with cheap metal-work and which may berapidly constructed by unskilled labor.

As the invention is especially applicable in connection with partitions,it will be illustrated and described in connection with such aconstruction, and a full description of a partition of the preferredform and the method of making the same will now be given in connectionwith the accompanying drawings, forming a part of this specification,and the features forming the invention will then be specifically pointedout in the claims.

In the drawings, Figure 1 is a vertical section of the partition inprocess of construction. Fig. 2 is a side elevation of the constructionbefore filling with concrete, partly broken away for purpose ofillustration. Fig. 3 is a horizontal section on the line 3 of Fig. 2.Fig. 4 is a vertical section of the completed partition.

Referring to said drawings, A is the ceiling and B the floor, betweenwhich the partition is formed, which ceiling and ioor may be of anysuitable construction. Extending from ceiling to floor are a series ofupright studs C of the width desired for the thickness of centralfilling in the partition, said studs being shown as channel-irons, whichis preferable for strength, and as formed with bent ends l() at top andbottom, by which the studs are secured to the ceiling and floor. It willbe understood, however, that these studs may 5o be of any other suitableform and secured to the ceiling and floor in any suitable manner. Uponopposite sides of these studs are secured sheets of woven or netted wireor perforated or expanded sheet metal or centers of any other suitablereticulated metal, so as to form ahollow space between the reticulatedmetal on opposite sides of the studs, the construction shown beingformed of common wire lathing D, with rods 11 interwoven atsuitableintervals, and the sheets of wire lath- 6o ing are shown assecured to the studs C by tying the rods ll to the studs by wire ties,although it will be understood that the lathing may be otherwise securedto the studs. The hollow space formed between the metal lathing D onopposite sides of the studs C is to be filled with a body of concrete orsimilar coarse fireproof material, which is to be filled in while in aplastic state and allowed to harden, so as to form a rigid partition,the 7o plastic material being held in place by the metallic lathing Dwhile setting, keying into the metallic lathing, so as to form anintegral structure t-herewith, and in turn after setting forming a keyfor the plaster which is pref- 7 5 erably used as a finish and appliedsubsequently on opposite sides of the structure, thus forming apartition finished on both sides with plaster held by the metalliclathing and concrete. The lathing or other re- 8o ticulated metal D usedin the structure is preferably of quite large mesh, so as to permitsuitable plastic material to be forced through the meshes of the metalfor filling the space between the two centers of reticutated metal, itbeing preferable to use for iilling this space a coarse strong material,such as the cinder-concrete now usually employed in fireproofconstructions. The use of this coarse-mesh lathing or other reticu- 9olated metal also reduces largely the cost and weight of 'metal in thestructure.

The vertical stud C having been secured in place and the lathing D orother reticulaied metal placed in position on opposite sides of thestuds the process of building the structure is as follows: Upon the sideof the `studs opposite to that from which it is desired to apply theconcrete in fillingavertical mold frame or centering is supported, thiscentervroe ing being shown in the construction as conssting of verticalbars E, which extend from floor to ceiling and are preferably made intwo parts arranged to slide on each other for adjustment and heldtogether by bands 13, so that the same bars E may be used with ceilingsof different heights. Two or more sets of the vertical hars E are used,two being shown in Fig. 2. These bars E of the mold framework orcentering may be supported in position in any suitable manner, but, asindicated in Fig. l, are supported from the floor by inclined struts F.Upon the face of these bars next the reticulated metal D and held by thebars in position against the metal, so as to support the latter whilethe concrete is being applied and forming a moldframe for the concrete,are boards G, which are preferably separate boards built edgewise oneach other to the height required in the structure, this feature,together with the vertical adjustable bars E, providing a mold frame orcentering which may be used with spaces between floors and ceilingsdiffering widely in height. The mold frame or centering having beenplaced in position against the reticulated metal D on one side of thestuds C the concrete or similar plastic material is filled in throughthe reticulated metal on the opposite side preferably by supporting atable, such as table H in the drawi-ngs, upon the metal, from which theplastic material may readily be forced in through the Y meshes of themetal to fill the space within the partition, being molded against themold frame or centering formed by the boards G. The table H is shiftedupward as the filling process proceeds, the table being constructed.

in any suitable manner, so as to be readily attached to and detachedfrom the reticulated metal, as desired. In the construction show' thetable is formed with hooks 3, which hook over the rods 1l of the lathingand is supported by hinged struts 4, engaging in the meshes of thelathing. It will be understood, however, that the mold board orcentering upon one side of the structure may be used with the plasticmaterial iilled in in any suitable manner, either through the meshes ofthe reticulated metal on the opposite side of the partition or fromabove before all the reticulated metal on the opposite side from thecentering is put in place. After the space within the partition betweenthe two centers of reticulated metal has been filled in the mold boardor centering is removed, and after the plastic material in the partitionhas set the opposite sides of the partition are finished by coating withplaster P, which keys onto the lathing and portions of concrete whichproject through the meshes of the lathing, thus forming a very strongconstruction.

It will be understood that this construction may be used with plasteronly on one side in case the construction is to be placed adjacent to awall instead of forming a partition, or

that such construction may be used'without finishing in plaster oneither side. The construction is especially designed, however, forpartitions and similar constructions finished with plaster on oppositesides.

It will be seen that the construction is very simple, strong, anddurable, While at the same time it may be made very cheaply with metalof large mesh and requiring no labor of special skill. The centralfilling of concrete or other plastic material reduces largely the amountof plaster required as compared with previous partition constructions inwhich the plaster is applied to the metallic lathing in forming eithersolid or hollow partitions without such a body of plastic material as abase for the plaster, thus aiding also in securing a cheap constructionof great strength.

The method of making a vertical reproof constructionwhich consists in erecting two vertical centers of reticulated metalarranged with a space between them, applying a mold frame or centeringon the outside of one of said centers, and filling the space betweensaid centers With a body of concrete or similar plastic material appliedin the plastic state and molded against said mold frame or centering,substantially as described.
